The procedure involves inserting a tube into the urethra through the opening at the end of the penis. It allows the doctor to visually examine the complete length of the urethra and the bladder for polyps, strictures (narrowing), abnormal growths, and other problems.
The outlook for men diagnosed with prostate cancer has never been brighter. Doctors now have a variety of ways to treat prostate cancer, including surgery, radiation, and drugs that slow the growth of cancer cells. Both the safety and effectiveness of prostate cancer treatments has been steadily improving.
That’s good news, of course. But with so many different approaches to prostate cancer treatment, each with its own benefits and risks, weighing your options and choosing the most appropriate treatment...
Cystoscopes are tubular instruments equipped with lights and viewing devices used to examine the interior of the urinary tract. There are two types of cystoscopes: a standard rigid cystoscope and a flexible cystoscope. The choice of which scope to use depends on the purpose of the exam.
In both methods, the test is carried out very similarly, with the exception of positioning. With the standard rigid cystoscope, you lie on your back with your knees up and apart. The urethra is cleaned and a local anesthetic to numb the area is applied. The scope is then inserted through the urethra into the bladder.
If your doctor uses a flexible cystoscope, this position is not required. Your doctor will help you find a comfortable position.
During the procedure, water is inserted through the cystoscope and into your bladder. Your doctor will ask you a series of questions regarding how you feel when your bladder is filled. When the bladder is full of water, it stretches. This allows your doctor to view the entire bladder wall.
If any tissue appears abnormal, a biopsy (tissue sample) can be taken through the cystoscope to be analyzed.
The entire procedure generally takes about 15 to 20 minutes.
Does the Test Hurt?
You may feel discomfort as the cystoscope is placed into the urethra and bladder. You will probably feel a strong need to urinate when the water fills the bladder. If a biopsy is taken you may feel a slight pinch.
After the procedure, the urethra may be sore and you will feel a burning sensation during urination for a day or two.
What Are the Risks of Cystoscopy?
The risks of having a cystoscopy include:
Bleeding from biopsy area (slight risk)
Rupturing of the bladder wall (slight risk)
A condition called hyponatremia which upsets the natural balance of sodium in your body
Contact your doctor if you notice any of the following after the cystoscopy:
